Carburetor Question PLEASE :)

The carb on my truck is a Holley R-8780 ( I am thinking from the numbers on pic) but I can't find a rebuild kit for it. Anyone know if I can find one, or do I need to just go with a new carb?

Thanks!

BTW....the truck came new with a 307 which got blown a few years into having the truck (I know the original owner) and he replaced it with a '72 (or so) 350. He isn't sure what it came out of and not sure if he kept the original carb or not. He is a little old...

That carb you have should be a replacement carb for a Rochester 2 bbl.

Thanks.... I had checked there already and they list a R-8779 then R-8781. Just wondering if one of those will work.
Thanks for the suggestion!

If you look on the Holley website, they list the kit for a r-8780a. Part# 3-875 kit.
